I would like everybody, debunkers and truthers alike, to state as consisely as possible your working hypothesis of what happened on 9/11, who did it, how they did it, and why they did it."
Thank you.
Background:
Emboldened by the USSR's humiliating exit from Afghanistan and crediting themselves with a military victory and (less credibly) with toppling the Soviet regime, OBL and associates formed a loose organization dedicated to violent jihad to overthrow "oppressors" of Muslims, including secular Arab regimes and other enemies around the world.
Gulf War I and its aftermath was perceived by OBL and associates as US occupation of the "land of the two holy cites" with the consent of a corrupt Saudi monarchy. The USA assumed the position of enemy #1 for Bin Laden and associates, leading to repeated attacks on American interests (most notably the embassies and USS Cole).
Attacks:
By 1999 - 2000, AQ decided to launch a major attack inside the US.
KSM, who initially brought the idea to Bin Laden was given the Sheik's approval to proceed with his plan.
The 19 eventual hijackers, selected in Afghanistan to become "martyrs", were sent over the ensuing months to the US to prepare, train for and carry out the attacks. Unclear is whether there was intended at the beginning to be a 20th hijacker. Possibly Ramsi Binalshib. Logistical and financial assistance was provided to the 19 through KSM, Binalshib and others affiliated with AQ.
The 19 AQ-assigned operatives, on the morning of September 11, hijacked the four flights, UA93 and 175, AA11 and AA77, the hijack teams assigned in an order that is clear from the flight manifests.
AA11 was crashed into WTC1 by Mohammed Atta and UA175 by Marwan Al-Shehi crashed into WTC2 igniting massive fires across multiple floors and killing hundreds of innocents inside the airplanes and towers within an instant and scores of injuries outside from falling debris. Hundreds more innocents were trapped above the impact floors being increasingly overcome by the massive heat and thick smoke, leading many to jump or fall from the upper floors to the ground.
AA77 was crashed by Hani Hanjour into the Pentagon killing scores of innocent victims on the ground and airplane passengers, and igniting a massive fire inside the Pentagon, causing the section of building above the impact to collapse some minutes later.
In New York, the WTC towers, both heavily engulfed in flames, showed increasing signs that they were in danger of collapse.
The perimeter columns bowing inwards were clearly visible on the east side of WTC2, WTC1 was visibly leaning to the south with massive fire across the south face at the impact floors.
Finally the floors of WTC2 gave way at the impact area, pulling in the east wall and causing the upper section to tilt and smash through the building below. WTC1 followed in a similar manner shortly afterwards. Damage to the surrounding area was extensive.
On UA93, intended to be crashed into the US Capitol, the passengers became aware of what was happening through phone calls made to loved ones. They fought to try to take back control of the airplane and the hijackers inside the cockpit decided to crash it into the ground in Shanksville to prevent that. Ziad Jarrah pointed the airplane down and crashed it into the ground. All aboard were killed.
Oh and WTC7 collapsed some hours later as a result of the large fires inside it which could not be fought.
The why:
To cause maximum damage possible (including in a political sense) inside the USA. To terrorize the US public. And to provoke the USA into a war in Afghanistan.
I believe in the mind of Osama Bin Laden was the idea that the USA as a world power could be broken by military defeat in Afghanistan in the same way he believed his mujahideen broke the Soviet Union.
And by breaking the USA and its influence around the world, then everything else would follow. Israel could be routed, the secular Arab regimes toppled and the corrupt Saudi monarchy replaced.
And now he's dead.
I don't understand how some folks have so much difficulty figuring out the above.
